如何在iOS中制作自定义按钮？

Question

默认的iOS UI很好，但是如果我想为按钮使用图像，那我该怎么做-是OpenGL吗？

Answer 1

Make the button a "custom button" type in interface builder. Then set the background image to be whatever you want the background to be.

Unfortunately the default button style is a little boring. You'll need to find or make a button with an image editor.

Answer 2

UIButton has a lot of support for custom buttons. In the nib (or storyboard or whatever), just click on the button and set its "Type" to "Custom" in the attribute inspector on the right side of the screen. Then, just below that, set the State Config to the sate you'd like (default, selected, etc) to customize, and set Image attribute to the image you'd like.

That image must be part of the project first before it will show up in the Image attribute (or in the app). You can add the image to the project simply by dragging it into the file navigator on the left side of the screen.

Answer 3

You can use images for buttons using a few simple lines of code:

// code to set image for button at normal state
[myButton setImage:[UIImage imageNamed:@"buttonImage.png"] 
          forState: UIControlStateNormal];

You can also use Xcode to change the type to "Custom" then you can set images for each button "state."

You can read more about UIButton states here

Answer 4

You can simply use PNG files that you create yourself. The UIButton class allows you to use custom images for all the different states of the application.

You don't really need to do custom rendering yourself, but if you really want, you can use UIKit to draw the images yourself in code (no OpenGL involved): http://developer.apple.com/library/ios/#documentation/2ddrawing/conceptual/drawingprintingios/graphicsdrawingoverview/graphicsdrawingoverview.html

Answer 5

You can do it by setting image or backgroundImage properties of a UIButton . If you want your button to look nice when the size changes, you can use stretchableImageWithLeftCapWidth:topCapHeight: method of UIImage , with an appropriate image.

You may also want to use a custom component if it satisfies your need.

Answer 6

its very easy

change this two thing.Change "type" round rectangle to custom and drag image to project and select it as background .Run and Go
